Variable folding devices for web-fed rotary printing presses are known from U.S. Pat. This known folding device has a cutting cylinder arranged in the stacking cylinder, between the stacking cylinder and the cutting cylinder, the printed material supplied via the pulling cylinder and the guide tongue is cut, Then, it is further guided to the folding cylinder via the belt guide which is in contact with the stacking cylinder. The stacking cylinder with the cutting groove device, the gripper device and the folding blade device is format-adjustable, i.e. the individual functional units mentioned above are format-adjustable. For this reason, speed differences occur due to the high peripheral speed of the stacking cylinder, especially when small formats are processed and the speed of the fed paper web is low. However, such pre-loading of the paper web causes a relaxation of the paper web when it is cut,
As a result, the cut end of the paper web may pop out of the entry point between the cutting cylinder and the stack cylinder. DE 1611292 discloses the disposition of guide tongues between the entry cylinder between the cutting cylinder and the stack cylinder and the pulling cylinder, but with this guide tongue. However, it is impossible to completely prevent the paper web from bouncing back, resulting in a relatively large folding error,
The "blockage" may cause a failure in the folding device.

度で接触している。The cylinder portion of the folding device comprises a stacking cylinder 1 and a cutting cylinder 2 cooperating with the stacking cylinder 1. The cutting cylinder 2 has two cutting cutters 3 on its outer peripheral portion, and the stacking cylinder 1 has three or five cutting groove devices, gripper devices and folding blade devices on its outer peripheral portion, respectively.
In FIG. 1, however, only the corresponding cutting groove 4 and the gripper 5 cooperating with the cutting cutter 3 are shown. The stacking cylinder 1 rotates in the direction of arrow A. The paper web 13 passes in the direction of the arrow B through the known driven pulling cylinders 6, 7 and reaches a belt guide system which is arranged above the cutting cylinder 2 and is indicated generally by the reference numeral 8. This belt guide system 8 comprises a spindle or rollers 9, 10, 11, 12
It is composed of a plurality of belts 15 which are guided along the axial direction and are arranged side by side in the axial direction, and the roller 11 of the rollers 9 to 12 is driven via the cutting cylinder 2. The belt guide system is the last pulling drum pair 6,7
From the entry point 16 between the cutting cylinder 2 and the stacking cylinder 1.
It extends to just before. The belt guide system of the second embodiment, which is generally designated by the reference numeral 17, includes rollers 10, 11,
12 and 18, in which case the roller 18 is seen in the paper web transport direction (arrow B) and the pulling drum pair 6, 7
Located in front of. With such a configuration, the belts 19 (see the alternate long and short dash line) arranged side by side in the axial direction also extend between the pulling drums 6 and 7. Also in this embodiment, the roller 11
Takes on the drive function of the belt guide system 17.
The belts 15 and 19 used alternatively in the belt guide systems 8 and 17 are in contact with the outer peripheral surface of the stacking cylinder 1 at a small winding angle.
